1. How are kidney stones broken down?

  • Intense beams of strongly ionising X-rays are fired at the stones.
  • An ultrasound beam concentrates high energy waves at the kidney stone and turns it into sand like particles.
  • Many weak ultrasound waves are reflected off the stones.
  • A weak concentration of X-rays are fired at the stones.
